Next, we made a calibration curve so that we could find the unknown concentrations for SF6 and CF3SF5 in our triple standard. To make the calibration curve, we needed to find the area under the peak in the chromatogram at…

Restoring the GC
by Jon Vardner •
We restored the Gas Chromatograph (GC) after a year long hiatus. The GC took a while to warm up, but thankfully it started running after a few days. Here’s a picture of the GC that we used. After the GC warmed up,…
Making the Triple Standard: N20, SF6, and CF3SF5
by Jon Vardner •
The first step of the project was making the triple standard gas containing N20, SF6, and CF3SF5. We needed CF3SF5 in the cocktail so that we could find its diffusion coefficient (the purpose of the experiment). We added N20 and SF6…
